Definition
In cybersecurity, a data center architecture encompasses various aspects, including design, layout, predefined configurations, and the entire infrastructure within a data center. It is configured to ensure consistent data integrity, confidentiality, and availability.
Moreover, it is supported by a range of security systems, tools, and strategies to protect data center assets in the event of threats or vulnerabilities.
Common Application of Data Centers in Cybersecurity
- Network segmentation and micro-segmentation: Network segmentation divides data center networks into distinct zones to prevent potential attackers from moving laterally. Each zone has its security policies, tools, and strategies. Micro-segmentation adds an extra security layer by isolating workloads and applications, significantly making it difficult for attackers to move laterally within the network.
- Multi-factor authentication (MFA) for access: MFA requires users to undergo various authentication steps and present multiple verification forms to access information in data centers. This helps to prevent unauthorized access even with a leaked or stolen password, as the attacker will need another factor (like biometric data or a unique access token) to gain access.
- Firewall and intrusion prevention system (IPS) configuration: Firewalls help control inbound and outbound data traffic, acting as a barrier between trusted and untrusted networks. IPS, on the other hand, helps identify and prevent malicious activities by analyzing inbound data traffic.
